As I needed a rear pulley very quickly, because of premature wear, almost (10000km) I decided to buy the first one that was almost identical to the ratio level, it is 2' wide and 65 teeth, it my necessary to modify and change the inner diameter with an offset inside the expander 3 mm which acts as a centering bore for the new brand BDL this pulley, the pulley is a central thickness of 5/8' instead of 3/4' approximately, therefore j did it as a flange that the screws is identical. I hope it shines especially for its longevity.
